Serial No. 687,040.

The reference numeral 1 denotes a portion of a door having the edgethereof provided with a mortise or recess 2 to accommodate a rectangularlock casing 3, said casing being retained within the door by a faceplate 4:, screwed or otherwise connected, as at 5 to the door. The plateat has bolt openings G and 7 and a latch opening 8. The sides of thedoor 1 are provided with escutcheon plates 9 screwed or otherwiseconnected as at 10 to the door. The plates 9 have openings 11 incommunication with openings 12 and 13 provided therefor in the door 1and the lock casing 3. The plates 9 have key openings 14 incommunication with similar openings 15 in the side walls of the casing3, these openings permitting of a key 16 being inserted in the lockcasing 3. The plates 9, the door 1 and the casing 3 support a knobspindle 17 having knobs 18. The spindle 17 within the casing 3 isprovided with oppositely disposed lugs 18 for shifting a spring pressedlatch 19 that extends through the opening 8. The latch 19, the spindle17 and the remainder of the latch operating mechanism is of the ordinaryand well known type common to various types of door locks. I do notclaim the latch mechanism as my invention and have simply illustratedthe same to identify its location relatively to the other mechanism ofthe lock.

Arranged within the openings 12 are permutation mechanisms, eachmechanism comprising a barrel 20 having the outer end thereof providedwith a peripheral flange 21 that is notched or roughened, as at 22whereby the barrel can be easily revolved. The inner end of the barrelhas an integral gear wheel 23 and arranged within the barrel is arevoluble tubular operating member 24. The outer end of the member 24has a peripheral flange 25 that is. notched or roughened, as at 26. Theoperating member 24 has a longitudinal slot 27 at the inner end thereofand oppositely disposed lugs 28. Mounted upon the inner end of themember 24 is a cap 29 provided with openings 30 to receive the lugs 28.The cap 29 is slotted, as at 31 and the caps of the operating membersare connected by a transverse pin 32 that is eccentrically mountedrelatively to said caps. Each of the caps 29 is provided with a lug orhearing 62 projecting from the edge thereof and to which the pin 32 isconnected. The pin 32 by such an arrangement is eccentrically mountedrelatively to the caps 29.

Movably mounted in the operating member 24 is a cylindrical actuatingmember 33 having the inner end thereof provided with a beveled blade 34and the outer end thereof notched or roughened, as at 35. The member 33has a pin 36 extending into the slot 27 of the operating member 24, saidpin preventing the actuating member from rotating therein. The blade 34of the actuating member extends into the slot 31 of the cap 29 andinterposed between said cap and the actuating member 33 is a coiledcompression spring 37, said spring engaging in a socket 38 providedtherefor in the actuating member 33. The tension of the spring 37retains the outer end of the member 33 normally protruding from theoperating member 24. The plates 9 and the outer exposed ends of themembers 24 and barrels 20 are provided with numerals, as shown in Fig. 1and the operating member 24 and the barrel 20 can be revolved to producedifferent combinations of numerals, one of which places certainmechanisms in operatable po sition, as will hereinafter appear. The sidewall of the casing 3, adjacent to the upper end thereof, is providedwith a transverse shaft 39 and revolubly mounted upon said shaft is thehub 40 of a double gear wheel 41 that meshes with the gear wheels 23 ofthe barrels 20 of the permutation mechanism. The inner side of thedouble gear wheel 41 has a radially disposed crank 42 and when the gearwheel 41 is revolved by either of the permutation mechanisms, the crank42 engages the notched end 43 of an arm 44 pivotally connected by a pin45 to the wall of the casing 3. The lower edge of the arm 44 has a notch46 to receive the connecting pin 32 of the permutation mechanisms. Toprevent the double gear wheel 41 from freely revolving the wall of thecasing 3 is provided with a compression spring 47 frictionally engagingthe hub 40 of said wheel.

Movably mounted between the arm 44 and one of the permutation mechanismsis a cam member 48 having an offset end 49 that is slotted, as at 50 andretained in engagement with the wall of the casing 3 by a pin 51. Thecam member 48 is provided with a slot 53 having the walls thereof curvedand with a slot 54 having the walls thereof straight, the straight slotbeing located in proximity to the curved slot.

The wall of the casing 3 is provided with a guide rib 55 for a lockingbolt 56 adapted to extend through the openings 7. The locking bolt islimited in its outward movement by a shoulder 57 and the upper edge ofthe bolt is cut away, as at 58 to provide clearance for the permutationmechanism. One side of the bolt 56 is cut away, as at 59 to provideclearance for a detent 60 that is arranged between the bolt and thesidewall of the casing. The detent has a concave upper edge 61 adaptedto be engaged by lug or bearing 62 carried by one of the caps 29. Thelower edge of the detent 60 has a strap with a tooth 64 at one endthereof and a barrel 65 at the opposite end, said barrel being pivotallysupported by a pin 66, carried by the side wall of the casing. Connectedto the strap 63 adjacent to the barrel 65, as at 67 is a flatcompression spring 68 that rests upon a pin 69, carried by the side wallof the casing. The tooth 64 normally engages one or the other of notches70 and 71 formed in the lower edge of the bolt 56. Pivotally connectedto the bolt 56, adjacent to the shoulder 57, by apin 72 is a latch 73having the upper edge thereof provided with a small notch 74 and a largenotch 75. The lower edge of the latch is cut away, as at 76 and isengaged by the end of a coiled compression spring 77 carried by the bolt56. The free end of the latch 73 has a lug 78 adapted to engage a checkpin 79, carried by the inner end of the bolt 56. Engaging in the smallnotch 74 of the latch 73 is a pin 80 carried by a resilient catch 81having the lower end thereof secured, as at 82 to the wall of the casing3. The upper end of the catch is curved, as at 83 and extending underthe curved end 83 of the catch and adapted to elevate the same and movethe pin 80 of the catch out of the notch 74 of the latch 73 is thebeveled end 84 of a releasing member 85. The'member 85 is slidablymounted between guide pins 86, carried by the side wall of the casing 3and said member is pivotally connected by a pin 87 to a lever 88pivotally connected, as at 89 to the side wall of the casing. Theopposite end of the lever is retained normally upon the reduced end 49of the cam member 48 by a compression spring 90, carried by the sidewall of the casing.

Before describing the remainder of the lock, particularly the keyoperated mechanism, it is thought best to consider the operation of themechanism thus far described, as the key operated mechanism is somewhatsimilar to that operated by the permutation devices. The lock can bemanipulated from either side of the door and the first op eration isthat of rotating the barrel 20, which through the medium of the gearwheel 23 imparts a rotary movement to the double gear wheel 41. As thedouble gear wheel 41 is moved the crank 42 thereof engages the notchedend of the arm 44 and elevates said arm, the notch 46 releasing theconnecting pin 32, The connecting pin 32 is looked, as shown in Fig. 9of the drawings and the operating member 24 cannot be revolved. In Fig.10 the arm 44 is shown as elevated, releasing the connecting pin 32.

The next operation is to rotate the operating member 24c;-the barrel 20and the double gear wheel 41 being held stationary by the compressionspring 47. As the operating member 24 is moved the connecting pin 32 isshifted, also the actuating member 33 by reason of the pin 36 extendinginto the slot 27 of the operating member 2 1. As the pin 32 is shiftedthe cam member 18 is moved, as shown in Fig. 10, placing the straightslot 54 in registration with the slot 31 of the cap 29, whereby theblade 34: of the actuating member 33 can enter the straight slot 54:.The next operation is that of pushing upon the actuating member 33. Thebeveled blade 34 of this member passes into the straight slot 54 engagesthe end wall of the slot and elevates the cam member 48. The upper reduced end 49 of said member rocks the lever 88, lowers the releasingmember 85 and raises the curved end of the catch 81. The pin 80 of saidcatch is carried out of the notch 74 of the latch 7 3 and the spring 77elevates the free end of the latch, as best shown in Fig. 11. The upwardmovement of the latch is limited by the check pin 79. The next operationis that of again moving the operating member 24 whereby the connectingpin 32 will be shifted downwardly in the curved slot and ride into thelarge notch 75 of the latch 73. As the connecting pin rides into thelarge notch 7 5 of the latch 73, the lug or bearing 62 carried by one ofthe caps 29 engages the detent lowering said detent, placing the spring68 under tension and moving the tooth 6 out of the notch 71 of thelocking bolt 56. A further movement of the operating member 24: causesthe connecting pin 32 to shift the latch 73 and as said latch isconnected to the bolt 56, the bolt is shifted to a retracted positionwithin the casing 3, as best shown in Fig. 12. Such movement of theoperating member 24 releases the detent 60 and the tooth 6% immediatelyengages in the notch 70 locking the bolt 56 in a retracted position. Themovement of the operating member 24 is permitted by the actuating member33 assuming its normal position immediately upon the cam 48 having beenelevated and the latch 73 is elevated by the spring 77 before the cammember 48 is released by the actuating member 33. To shift the bolt 56to a locked position, the operating member 2 1 is revolved in theopposite direction, whereby the detent 60 will be lowered, the bolt 56shifted, the latch 73 lowered and locked by the pin 80 of the catch 81and a further movement of the operating member carries the connectingpin to the closed end of the curved slot 53. The barrel 20 can then bemoved whereby the arm 44: will be released to lock the connecting pin32, as shown in Fig. 9.

The key operated mechanism is located in the lower part of the casing 3and comprises a bolt 91 very similar to the bolt 56, a spring pressedlatch 92 very similar to the latch 73, a spring pressed detent 93similar to the detent 60, and a catch 94 similar to the catch 81, saidcatch having a pin 95 engaging in a notch provided therefor in the latch92. Pivotally connected to the side wall of the casing 3 by a pin 96 isa link 97 retained normally in engagement with a check pin 98 by acompression spring 99, carried by the side wall of the casing 3.Pivotally connected to the link 97 by a pin 100 is an ac tuating member101 supported at an angle to the link 97 by a flat spring 102, carriedby said link. The pin 100 protrudes above the member 101 beneath thecatch 94.

The key 16 has a bit 103 and said key can be freely revolved in onedirection within the casing 3. When the key is turned to the left orcounter clockwise the bit 103 engages the end of the member 101 and saidmember is lowered together with the link 97. The pin 100 rides intoengagement with the curved end of the catch 94 and said catch iselevated whereby the pin 95 will release the latch 92. The latch 92 islowered and when the key is turned clockwise, the detent 93 is elevatedreleasing the bolt 91 and said bolt is shifted to a retracted positionby the key engaging the latch 92. It is thought that the operation ofshifting the bolt 91 to an extended position will be apparent in view ofthe foregoing, as the member 101 can readily shift as the key is turnedcounter clockwise.

lVhat I claim is A lock comprising a casing, a bolt slidably mounted insaid casing, a spring pressed detent holding said bolt in adjustedposition, a latch pivotally connected to said bolt, a catch holding saidlatch normally stationary, means for engaging said catch to release saidlatch, and means including permutation mechanisms for actuating the lastmentioned means and shifting said latch and said bolt.

In testimony whereof I affix my signature in the presence of twowitnesses.
